Title: Ic testing apparatus
Inventor: YAMASHITA EISAKU
IPC: G01R31/28
Filed: 1989-07-03
Abstract: PURPOSE:To improve the electrical characteristics of a test signal by constituting an IC testing apparatus so as to incorporate the testing means of an IC to be tested, a feed means and a contact means in the same housing. CONSTITUTION:In an original oscillator 9, a pattern generator 10 and a timing generator 11, test signal data is formed in a conventional way to form test signal data. In this case, a test signal wire 16 becomes short. Therefore, the signal data is sent to pin electronics 12 in a state reduced in electrical deterioration through the short signal wire 16. A test signal is formed from the above mentioned test signal data by the pin electronics 12 and outputted from a performance board 4. A feed means 15 and a contact means 14 perform the same operations as those of conventional ones and an IC 7 to be tested is successively inserted in the performance board 4 to perform a test by the above mentioned method. In this case, since a cable can be shortened, the electrical characteristics of the test signal can be improved.

Title: Semiconductor device
Inventor: YOSHIMI MAKOTO
IPC: H01L31/10
Filed: 1983-09-20
Abstract: PURPOSE:To contrive to enable to perform the arithmetic operation of an element at higher-speed by a method wherein signal propagation is performed with light by using light and electric signal converting elements. CONSTITUTION:Plural pieces of light and electric signal converting elements 8, 9 and 10, which function respectively as a light-receiving part and a light-emitting part at the drain depletion layer region of an MIS transistor, are arranged on a semiconductor in such a way as to adjoin to each other at a prescribed distance (x). For example, the elements 8 and 10 are respectively a converting element for light-emission and the element 9 is a converting element for light- reception. When an electric signal is inputted in the elements 8 and 10, the electric signal is converted into an electromagnetic wave at the drain part of the element. The electromagnetic wave propagates along the interior of the semiconductor while being attenuated in the interior and is again converted into an electric signal at the element 9. As the signal transmits at the propagation velocity of the electromagnetic wave, signal delay due to the wiring capacity goes and the computing speed of the element is quickened. Moreover, as the element has been constituted in an almost same structure as that of an MOS transistor, a higher-integration also can be contrived.

Patent JP-S6328131-A (JP)
Title: Frequency controller by slip phase control ppl
Inventor: INOUE SHOJI
IPC: H03L7/197
Filed: 1986-07-22
Abstract: PURPOSE:To finely control a frequency by dividing a variable frequency division number by (n+q)(qnot equal to 0 integer) at each period T and adding or subtracting the output of a saw-tooth wave generator which generates the saw-tooth wave with the period T. CONSTITUTION:The (n) (n: positive integer) frequency-division results of a com parison frequency fR and the output frequency Fo of a VCO 11 are compared and detected by a phase comparator 15 and feedback to the VCO 11 is performed in a PLL so that the phase difference is constant. In this PLL circuit, the (n) frequency division is switched to (n+q) frequency division (qnot equal to 0 positive or negative integer) at every period T (T>=l/fR) and the saw-tooth wave with the period T is added (or subtracted) to the output of the phase comparator 15 by the saw-tooth wave generator 2. Consequently, a fine frequency is control lable even in a high frequency range where variable frequency division is impos sible unless a two-coefficient pre-scaler 12, and frequency control to a plus and a minus value is enabled. Consequently, an error in the reference frequency of a multichannel radio transmitter receiver due to temperature variation, etc., is finely corrected while a channel switching speed is held high.

IPC: H05K3/32
Filed: 1989-07-03
Abstract: PURPOSE:To contrive the improvement in a mechanical and chemical addhesive strength without electrical troubles such as the short circuit between foot prints or leads caused by a solder and, etc., by a method wherein after molding a bond reinforcing structure which has an uneven shaped surface on the foot prints of a printed circuit board, the heat-pressure bonding of the foot prints and the leads of a part is effected while interposing an anisotropic conductive sheet. CONSTITUTION:On a foot print 11, uneven shapes and pin holes 12 are formed at the same time as formation of patterns such as the foot print 11. After that, an anisotropic conductive sheet 3 is stuck to the whole region of a foot print part 10 by use of an addhesive agent. Over said sheet 3, the positions of leads 21 are adjusted to those of the foot prints 11 respectively, followed by the heat-pressure bonding from the above. When the leads 21 are thus pressed against the foot prints 11 by a pressure-bonding iron, the anisotropic sheet 3 under said leads 21 are especially pressed intensely and a conductivity appears there. Accordingly, the leads 21 are electrically conducted with the foot prints 11 and also, a part of the anisotropic conductive sheet 3 enters the pin holes 12, thereby strengthening an addhesive force.

When the object P does not exist in the area, a circular converged light spot is formed, but, when the object P exists in the area, an elliptic converged light sop is formed in the section 2. Therefore, the presence/absence of the object P can be detected from the shape of the light spot.

Title: Monostable multivibrator
Inventor: YAMADA HISAFUMI
IPC: H03K3/0232
Filed: 1981-10-29
Abstract: PURPOSE:To reduce the cost of monostable multivibrator which is used in a ghost eliminating circuit without deteriorating the function of the vibrator, by using a constant current to discharge a capacitor of a constant circuit. CONSTITUTION:The emitter of a discharging transistor TR102 is grounded via a resistor 123. As a result, it is eliminated that a large discharge current flows via the TR102 even at a time point when the TR102 is turned on. Thus the both- end voltage of a capacitor 103 drops gradually less than the base voltage S4 of a TR109. As a result, the TRs 104 and 109 are turned off and on respectively. The pulse width is varied for the masking pulse Pm given from an output terminal 117, and the rise of the pulse receives no effect. Thus the capacity can be reduced for the TR102.

Title: Power steering device of automobile
Inventor: KANAZAWA HIROTAKA
IPC: B62D6/02
Filed: 1982-10-02
Abstract: PURPOSE:To gradually increase the set load of a change-over valve at its early stage of actuation in response to the increase of vehicular speed by a method wherein the turning torque is controlled by increasing and decreasing in response to the vehicular speed. CONSTITUTION:During high speed running, a controller 40 is actuated by an output signal of a vehicular speed sensor 42 generated as the result of the detection of the high speed so as to put an electric motor 39 into high speed running. The high speed running of the motor 39 causes a control pump 36 also into the high speed running, resulting in increasing the delivery of the pressure oil of the control pump 36 and consequently raising the pressure in the reaction chamber 33 of the change-over valve 20 in order to increase the set load of the change- over valve 20 at its early stage of actuation. In this case, because the rate of pressure oil supplied to the reaction chamber 33 of the change-over valve 20 by the control pump 36 is controlled so as to correspond to the square root of the vehicular speed, the set load of the change-over valve 20 at its early stage of actuation toward the steering force is changed so as to increase in proportion to the vehicular speed.
